Question

The centripetal force is a real force which provides with the real interacting force of:

Options are:

a. mechanical

b. electrical

c. magnetic or gravitational

d. All of these

Please write the answer with a specific reason. thank u!

Answer 1

e...nun av abuv

Its the apparent foers av spinning bodees (like spin bukket av water on a rope & water dont fall out).

opposit av sentrifugal foers.

Answer 2

I think that all are possible.

a. Tension in a string can pull inward on something swinging in a circle.  Is that what is meant here by a 'mechanical' force?  I find that a confusing term.

b.  The electrical attraction to the nucleus pulls inward on orbiting electrons in an atom.

c.  The magnetic force on an electric charge moving in a magnetic field causes it to move along a curved path.

d.  Gravity provides the inward force on objects in orbit.

Answer 3

As well as the really poor spelling, the first answer is also wrong. Centrifugal force is a fictitious force (i.e. it does not exist)

Lets analyse these.

a) What exactly do you mean by mechanical force? Tension in a string can be a mechanical centrifugal force.

b) Electrons orbiting a nucleus could be described as having electrical centrifugal force, as there is a force towards the centre of the atom.

c) The force of a magnetic field on a charge causes it to travel in a circular motion, again centrifugal force.

d) Gravity is the force which holds things in orbit, again, circular motion, so a centrifugal force.

Maybe the question isn't specific enough, or perhaps somebody else will be able to expand here.

Hope this helps.
